Description of the Invention (), [Field of the Invention] The present invention relates to a "device capable of increasing the speed of a permanent magnet type horse far, and in particular to a permanent magnet The magnetic motor device has a plurality of sets for sensing changes of different rotating magnetic poles of the rotor magnet, and causing the stator exciting coils to have different on-time differences, and different strength motor torque constant KT values, so that the same motor produces a variety of different motor speeds. Manufacture of a motor with high operating efficiency must be designed with an appropriate torque constant τ, depending on its operating range, as shown in the following formula: Ε = Κε · Ω Ke = B * D * L * Z / 2 τ = κτ · la Κτ = Β · D · L · Z / 2 Ε · Back-EMF voltage (Volt) Τ: Output torque (Nm) KE: Back-EMF constant Kτ: Torque constant Ω: Armature rotation speed (red / sec) I a: Armature current (Ampere) B: Air gap magnetic flux density (Gauss) D: Armature outer diameter (cm) L: Stacked thickness (cm) Z: Total number of conductors (turns) Torque constant τ in the above formula = Back electromotive force constant {^ value, and back electromotive force The number KE is inversely proportional to the armature speed Ω. Therefore, at a fixed back-EMF voltage Ε and the rated armature speed q is low, the back-electromotive force constant KE value will be relatively high, and the back-EMF constant at a high rated armature speed 0 The KE value will be relatively low, so if the motor is designed at a higher rated electrical frame speed, the torque constant kt will be relatively low. If the wire motor is operated at a low continuous rotation speed, it must use a higher armature current Ia to increase the torque.

Description of the invention () Value (Ϋ-· I a) 'If the motor does not have a higher torque constant & value |] due to (Κτ = Κε)' (Ε = Κε · Ω), the motor will not reach a higher value The rated operating speed. According to the embodiment of the present invention, a motor not only has a higher torque constant TK. The value is also caused by the magnetic sensor that can be switched to the sensing angle in advance, and the armature response of the motor is generated. The effect of the field weakening control results in a decrease in the air gap magnetic flux density of the electrode. From the foregoing formula, Kg = g · Ε > · Ι ^ · Z / 2 and Ε = Κε · Ω, because the armature air gap magnetic flux density decreases by 8 and the back electromotive force constant κε value inevitably decreases, so the armature speed Ω will inevitably increase. Disadvantage] In view of the conventional motor torque torque constant Kτ value is a single value, but a horse, if usually works in a lower speed range and occasionally operates in a higher speed range (such as a portable electric scooter), In order to make the motor run to the highest speed range used infrequently when necessary, because κε: Κτ, (Ε-Κε · Ω), (τ: κτ · ia) if the value of back-EMF voltage is not twisted, i constant ττ value and The back-EMF constant κε must be lowered to improve the printing by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 部 ΐ t _ to not: the maximum speed range for normal operation, but because the value of δ〶Κτ becomes smaller and the motor works at a constant working speed Range, because — & low ~ inverse 4 Chuanwei Ding — Κτ · ^ that is, the armature current la value must be proportional to the increase in torque τ value, but the increase of the electric power :: Electric hold ^ P: Motor Coil loss power Denkawa L R: · Coil impedance
